If you're in the market for an unlocked iPhone 5 and need to fit your existing SIM card in it, you can actually cut your current SIM card down to nano size at home.

Most people won't need to do this, but if you've bought an unlocked iPhone 5—say, if you are using it on an unsupported carrier—you can convert your current micro-SIM card into a nano-SIM with nothing but a pair of scissors (or, if you want to be really precise, an Xacto knife). There are a ton of guides for this around the net, but we really like this one from TechnoBuffalo, which provides a template that you can print out and size up exactly. Note that some guides say you need to sand the cards thickness down, too, but this shouldn't be necessary. Check out the video above from iPhoneZen to see what the process entails, and hit the link below to read more.
